Wisdom Teeth: Potential Problems
Poorly positioned impacted wisdom teeth that are not removed have the potential to cause problems throughout your life and should not be ignored.
- Impacted teeth may grow sideways, partially emerge from the gum tissue, and even remain trapped beneath the gum and bone. They can take many positions in the bone as they attempt to find a pathway that will allow them to successfully erupt.
- When they are partially erupted, the opening around the teeth allows bacteria to grow and will eventually cause an infection. The result: swelling, stiffness, pain, and illness.
- The pressure from the erupting wisdom teeth may move other teeth and disrupt the orthodontic or natural alignment of teeth.
- The most serious problem occurs when tumors or cysts form around the impacted wisdom teeth, resulting in the destruction of the jawbone and healthy teeth.

The most frequent clinical problem we see is pericoronitis, (a localized gum infection). Without enough room for total eruption, the gum tissue around the wisdom tooth can become irritated and infected, resulting in recurrent pain, swelling, and problems with chewing and/or swallowing.
Non-infectious diseases may also arise in association with an impacted wisdom tooth. Cysts are fluid-filled “balloons” inside the jaw bone that develop as a result of impacted teeth and slowly expand destroying adjacent jaw bone and occasionally teeth. They can be very difficult to treat if your wisdom teeth are not removed in your teenage years. Although rare, tumors can be associated with the delayed removal of wisdom teeth.
Impacted wisdom teeth may contribute to crowding of your teeth. This is most noticeable with the front teeth, primarily the lower front teeth and is most commonly seen after a patient has had braces. There are a number of factors that cause teeth to crowd after braces or in early adulthood. Retained, impacted wisdom teeth may be a contributing factor. Unless you have an active problem when you see the oral surgeon, the reason for removal is primarily to prevent long-term damage to your teeth, gums and jaw bone.
Damage to Adjacent Teeth:
If there is inadequate room to clean around the wisdom tooth, the tooth directly in front, the second molar, can be adversely affected resulting in gum disease, bone loss around the tooth, and/or decay.
What if I don’t have my wisdom teeth removed as a teenager or young adult?
As wisdom teeth develop, the roots become longer and the jaw bone more dense. When it is necessary to remove impacted wisdom teeth in your thirties, forties or beyond, the post-operative course can be prolonged and there is a higher complication rate. Treating these complications is often more difficult and less predictable than with a younger patient. Healing may be slower and the chance of infection can be increased.
If your impacted wisdom teeth are not removed in your teenage years or early in your twenties and they are completely impacted in bone, it may be advisable to wait until a localized problem (such as cyst formation or localized gum disease and bone loss) develops.
In general, you will heal faster, more predictably and have fewer complications if treated in your teens or early twenties.
